Certified Backflow Testing in Erie, CO
Keep your drinking water safe and ensure full municipal code compliance. Our certified cross-connection technicians test, rebuild, and certify backflow assemblies across Weld and Boulder Counties. We provide direct electronic reporting to the Town of Erie.
Cross-Connection Control & Colorado CDPHE Regulation 11
Under CDPHE Regulation 11 and IPC codes, commercial properties and dedicated irrigation lines must install backflow preventers. Properties must also test and certify these assemblies annually.
Backflow happens through two distinct hydraulic events: backsiphonage and backpressure. Backsiphonage occurs when municipal water pressure plummets during main ruptures. Negative pressure then pulls untreated water from irrigation lines into culinary grids. In contrast, backpressure occurs when downstream pumps exceed city pressure, forcing non-potable liquids backward.
Backflow Assembly Types We Test & Service
Different hazards demand different assembly designs. Our certified cross-connection control specialists test, inspect, repair, and install all approved configurations:
- RP / RPZ (Reduced Pressure Zone Assemblies): Required for maximum-hazard applications where toxic chemicals, glycol boiler fluids, commercial kitchens, or medical equipment connect to water supplies. Features two independently acting check valves separated by an automatic hydraulically operated differential relief valve.
- DCVA (Double Check Valve Assemblies): Approved for low-to-medium hazard commercial systems and fire sprinkler risers where backpressure is possible without toxic substances.
- PVB (Pressure Vacuum Breakers): Standard protection for residential and commercial landscape sprinkler manifolds. Engineered with an independently acting spring-loaded check valve and spring-loaded atmospheric air inlet.
- SVB (Spill-Resistant Vacuum Breakers): Ideal for indoor installations or compact mechanical closets where traditional PVB water discharge cannot be accommodated during startup cycles.
Precision 5-Valve Differential Gauge Testing
Testing a backflow preventer requires precision instrumentation. Our certified inspectors utilize calibrated 5-valve differential pressure gauges to measure the exact performance of each mechanical component under operating pressure:
- Inlet & Outlet Shutoff Integrity: Verifying isolation ball valves shut drop-tight with zero bypass or seat leakage.
- Check Valve 1 Delta P: Measuring the differential pressure drop across check valve 1 to guarantee positive closure (minimum 5.0 psid on RPZ assemblies).
- Differential Relief Valve Opening Point: Ensuring the relief valve vents to atmosphere at minimum 2.0 psid before water can flow backward.
- Check Valve 2 Backpressure Resistance: Pressurizing the downstream side to verify check valve 2 seals flawlessly against reverse flow.
Same-Day Rebuilds, Parts & Winterization Protocols
If an assembly fails its annual test, you don't have to wait days or hire another contractor. Because Erie water contains 12–18 GPG hardness, mineral scale easily forms on internal valve seats and silicone poppets. Our service trucks are stocked with genuine OEM rebuild kits from Watts, Febco, Zurn Wilkins, and Ames. We can dismantle the valve body, clean internal scale, replace worn rubber discs and springs, and perform a successful re-test during the same appointment.
In the fall, Front Range sub-zero cold snaps pose catastrophic freeze risks to exterior PVB assemblies. We provide seasonal blowout, shutoff, and freeze-protection services to safeguard your assembly from cracked brass bodies and expensive spring replacements.
Direct Municipal Compliance Reporting
Managing commercial compliance shouldn't be stressful. Once testing is complete, our technicians affix a state-compliant tag directly to the device. We electronically file certification with the Town of Erie Water Department. Automated notifications ensure your next inspection is scheduled before deadlines.

Backflow Testing FAQs for Erie, CO
Why is backflow testing mandatory in Erie, CO?
Backflow testing is mandated by the Colorado Department of Public Health and Environment (CDPHE) Regulation 11 and Town of Erie municipal ordinances to protect the public drinking water supply. When water pressure drops unexpectedly—due to a main break, heavy firefighting demand, or construction work—unprotected connections can siphon non-potable water, fertilizers, chemicals, and bacteria backward into the public water mains. Certified annual testing ensures mechanical check valves and relief ports hold pressure and operate reliably under actual backpressure and backsiphonage conditions.
What types of backflow prevention assemblies require annual certification?
Any property with an active cross-connection hazard requires annual certified testing. In Erie, this includes commercial facilities (restaurants, medical offices, car washes), multi-family residential complexes, fire sprinkler riser lines, and commercial or HOA dedicated lawn sprinkler systems. The primary assemblies tested are Reduced Pressure Backflow Preventers (RP/RPZ), Double Check Valve Assemblies (DCVA), and Pressure Vacuum Breakers (PVB).
What happens during a certified backflow test?
An ASSE or ABPA-certified cross-connection technician connects a calibrated 5-valve differential pressure gauge kit to the test cocks on your backflow assembly. The technician verifies each check valve closes tightly against backpressure, measures the differential pressure drop across check valves 1 and 2, checks that shutoff valves seal completely without bypassing, and verifies that the atmospheric relief valve discharges at or above 2.0 PSI differential. Results are documented on official state compliance forms and submitted directly to the Town of Erie Water Department.
What happens if my backflow assembly fails its annual test?
If an assembly fails due to debris on a valve seat, worn rubber check discs, or fatigued springs, our technicians carry complete manufacturer rebuild kits on truck for Watts, Febco, Wilkins, and Ames assemblies. In most cases, we can clean, rebuild, and re-test the unit on the spot during the initial visit, eliminating return trip charges and keeping your property fully compliant before the municipal deadline expires.
